How should waterproof connectors be selected?

When choosing waterproof connectors, here are some factors to consider:

1. Material durability: Make sure the materials used in the connector have good waterproof performance. Common waterproof connector materials include rubber, silicone, etc. Please make sure that the selected material can prevent moisture from penetrating into the connector and can resist oxidation and corrosion.
2. Waterproof level: Understand the waterproof level of the connector. Common waterproof level standards include IP68. IP68 means that the connector has good protection against dust and long-term immersion in water. Select the appropriate waterproof level according to the needs of the actual use environment.
3. Connector type: Select the appropriate connector type according to the required connection method. Common waterproof connector connector types include plug connection, threaded connection, snap connection, etc. Make sure that the selected connector type can be firmly connected and has waterproof function.
4. Capacity requirements: Select a suitable waterproof connector according to the capacity requirements of the current and signal to be transmitted. Make sure that the selected connector can meet the electrical and signal transmission requirements of the actual use scenario.
5. Installation convenience: Consider the convenience of installing and removing the connector. Waterproof connectors usually need to be installed correctly to ensure waterproof effect. Choose a connector type that is easy to install, such as a plug-in connector or a connector with a simple tightening mechanism.
6. Supplier reputation and technical support: Choose a supplier with a reliable reputation and good technical support. The quality and performance of waterproof connectors are related to the reliability and durability of the equipment used.

Product high and low temperature test:

What is the purpose of product high and low temperature test?

High and low temperature test, also known as high and low temperature cycle test, is one of the product environmental reliability tests. Basically, all products are stored or operated under a certain temperature environment. The temperature in some environments will change constantly, sometimes high and sometimes low. For example, day and night in some areas with large temperature differences. Or the product repeatedly enters and exits high temperature and low temperature areas during transportation, storage, and operation.

This high and low temperature environment may reach 70°C or higher when the temperature is high, and the temperature may reach -20°C or even lower when the temperature is low. This constantly changing temperature environment will affect the function, performance, quality and life of the product, accelerate the aging of the product, and shorten the service life of the product. If the product is in this large-scale alternating high and low temperature environment for a long time, it needs to have sufficient resistance to high and low temperature cycles.

In this way, we need to simulate certain environmental conditions and conduct high and low temperature tests on the products to understand the performance of the products in this regard. If the test results do not meet the standards we set, we will improve the products according to the test conditions and then retest until they are qualified.

How many hours does the high and low temperature test of the product usually take?

How long the high and low temperature test takes depends mainly on which industry the sample being tested is mainly used in. The environment during use can almost determine the temperature required for the test. Then, after understanding the standards that the industry needs to meet, it will stipulate the storage time of the samples in high temperature and low temperature environments, and the number of high and low temperature cycles and the time required for the high and low temperature test chamber to increase and decrease the temperature, and the total time required for a high and low temperature test can be calculated.

For the electronic products industry, the high temperature power aging test widely used by manufacturers generally takes several or dozens of hours. The main function is to screen components with multiple potential faults. In fact, different industries have different requirements, and the actual duration of high and low temperature tests is generally based on the specific needs of customers
